| 1)电缆保护管载流量高、热阻系数低。 1) High current carrying capacity and low thermal resistance coefficient of cable protection tube. 2)电缆保护管使用时，与电缆间的摩擦系数低，电缆穿过时更方便。 2) When the cable protective tube is used, the friction coefficient between the cable and the cable is low, and it is more convenient for the cable to pass through. 3)电缆保护管加长了井距，减低了工井数量，降低了工程成本。 3) The cable protective pipe lengthens the well spacing, reduces the number of working wells and reduces the project cost.tongdiaof.71ix.comtongdiaoy.71ix.com tongdiaog.71ix.comtongzhong.71ix.comrenwu.71ix.comtongdiaor.71ix.com |
